I have been trying to figure this out for a long time now, my car goes lean as shit on 4000 rpm or 5000rpm and I haven't yet figured out why.
So far I tried
Cleaning MAF
Upgrading FPR
Cleaning ign coils
Changed spark plugs
Changed O2 sensor
Changed fuel filter

I have a pic of my driving on full throttle and as you maybe can see here is where the engine cuts and goes lean on both gears. (if anyone can figure out anything in this picture)
Black = RPM
Dark blue = Air Flow
Light gray = Injectors
Dark gray = Timing
Blue = AAC

It seems that every time AAC rises, the car hesitates and stalls just then, could that be it? Or is it just a coincidence?
There are no fault codes either
E: also it's an SR20, just in case
